Wrong foot

Ada (2 1/2) is all too familiar with the experience of trying to put her shoe on the wrong foot. She usually figures it out when she realizes she is having way too much trouble than would normally be expected from a harmless velcro shoe. The other day she was trying to put on her sock by herself and the sock just didn't seem to want to cooperate. She turned to me in frustration and asked, "It's the wrong foot?"
